What hypotheses Rust was formed on the window grills?

Answer 1

Rust typically forms on metal surfaces, like window grills, due to the presence of moisture, oxygen, and iron. The primary hypothesis is that when these elements interact, especially in the presence of water, they create an electrochemical reaction that leads to the oxidation of iron, forming iron oxide, or rust. Environmental factors like humidity, temperature, and exposure to salt or pollutants can accelerate this process, leading to more rapid corrosion. Additionally, if protective coatings are compromised, the likelihood of rust formation increases significantly.
